in a closed loop, does it matter if my flow goes, pump, rad, gfx, cpu, res ? i think i have asked before but cant remember what the out come was
It really doesn't matter what is where in the loop as the water temperature ends up evening out as it is a closed loop. That setup will be fine.
Opening your res and allowing them to escape usually solves this problem. If not, run thepump on its own (PC off) and rock ther computer left/right up down.
The foam like bubbles tend to happen to me when air is getting into the pump as it froths it up a bit. Make sure your res is full. Also as Fr4nk said, run the pump without the computer on and shift the PC around leaning on different angles so all the air can escape into the reservoir. Also make sure that th inlet to the res is below the waterline else you will get a lot of air in the loop.
